- OSspecific: chmod() -> chMod(), even although it's not used anywhere

- ListOps get subset() and inplaceSubset() templated on BoolListType

- added UList<bool>::operator[](..) const specialization.
  Returns false (actually pTraits<bool>::zero) for out-of-range elements.
  This lets us use List<bool> with lazy evaluation and no noticeable
  change in performance.

- use rcIndex() and fcIndex() wherever possible.
  Could check if branching or modulus is faster for fcIndex().

- UList and FixedList get 'const T* cdata() const' and 'T* data()' members.
  Similar to the STL front() and std::string::data() methods, they return a
  pointer to the first element without needing to write '&myList[0]', recast
  begin() or violate const-ness.

- ditched PrimitivePatchExtra in favour of a PatchTools class that is
  currently just a collection of static functions. They could equally well
  live within PrimitivePatch itself, but isolated also has its advantages.

- MeshedSurface, UnsortedMeshedSurface now have 'regions' instead of
  'patches' since they are more like a faceZone for meshed surfaces than
  patches. This might avoid confusion at a later stage.

- new members:  capacity(), two-argument resize()/setSize(), const storage()
- new static members: max_value(), packing(), etc.

- grammar in comments, namespace qualifiers, etc.

- uniform use of reinterpret_cast<foo*>(0) instead of
  reinterpret_cast<foo*>(NULL)

- make all static null() members inline since they are really only a cast:
      "*reinterpret_cast<foo*>(0)"

- can use 'XX.empty()' instead of 'XX.size() == 0', 'XX.size() < 1' or
  'XX.size() <= 0' or for simpler coding.
  It also has the same number of characters as '!XX.size()' and /might/ be
  more readable

- many size checking had 'XX.size() > 0', 'XX.size() != 0', or 'XX.size() >= 1'
  when a simple 'XX.size()' suffices

- The capitalization is consistent with most other template classes, but
  more importantly frees up xfer() for use as method name without needing
  special treatment to avoid ambiguities.

  It seems reasonable to have different names for transfer(...) and xfer()
  methods, since the transfer is occuring in different directions.
  The xfer() method can thus replace the recently introduced zero-parameter
  transfer() methods.
  Other name candidates (eg, yield, release, etc.) were deemed too abstract.

  - added boundBox(const tmp<pointField>&) constructor for use with
    coordinate systems
  - moved some methods from treeBoundBox to boundBox and use VectorSpace ops

- if mandatory is true, findEtcFile() will abort with a message (via cerr).
  This allows a non-existent file to be caught at the lowest level and avoid
  error handling in IFstream, which might not be initialized at that stage.

- moved findStrings from stringList to new stringListOps
  (helps reduce the influence on dependencies)
- findStrings can also do partial matches

 - using SizeInc to define the granularity in the SizeMult=0 needed?

- setSize() adjusts the addressable length only.
  Changed setSize(label) usage to setCapacity(label) or reserve(label)
  throughout. The final name (capacity vs. storageSize() vs. whatever) can
  easily be decided at a later date.
- added setSize(label, const T&), which may still not be really useful, but
  is at least now meaningful
- made shrink() a bit more legible.
- added append(UList<T>&)
- copying from a UList avoids reallocations where possible

The following bits of code continue to use the DynamicList::setSize(), but
appear to be legitimate (or the corresponding code itself needs rethinking).

- plain nTriangles() inline method for face class
  - triFace gets the same for symmetry
  - face::triangles(), face::trianglesQuads() return the number of faces generated
  - face::triangles() can append to a DynamicList

- boundBox::invertedBox is useful for initializing our own calculations
- NOTE treeBoundBox::greatBox is still in place, since it uses GREAT
  instead of VGREAT. If this is only historical, we can drop it.

 - operator+=  : add in the listed keys
 - operator-=  : remove the listed keys
 - operator&=  : intersection of keys
 - added xfer constructor (just in case)
 - moved labelHashSet typedef to HashSet.H, for consistency with the
   wordHashSet typedef being there and since it is used so often

- drop copy components constructors in favour of the xfer versions. Even if
  the caller sends through constant data, if will be automatically promoted
  to xfer (via a copy operation).
